The German campaign focuses on slowing the advance of the Soviet troops, while the Soviet campaign is all about breaking through the enemy's resistance. However, the player does not have to do all this on foot: Using their computers, tacticians will control tanks, including the famous German battle tank Panzerkampfwagen VI or Königstiger and the Russian Stalin tank JS2, or fighter planes such as the Focke Wulf 190 and dive bombers like the Stuka or the Petlyakov PE-2.

Online is where the battle really heats up in Iron Front – Liberation 1944: Players can either complete missions cooperatively or compete with each other in special multiplayer modes such as Capture the Flag or Attack and Defense. Iron Front – Liberation 1944 also includes an extensive mission editor, enabling players to intuitively create their own missions and share them with their friends online, thus guaranteeing that there will never be a shortage of new missions.
